TIL-LAY|NG ATTACHMENT FOR MoLE-PLOws.

SPECIFICATION forming part of Letters Patent No. 355,588, dated January 4,1887.

Application tiled July 19, 1886. Serial No. 208,424. (No modcl;

To all 10710711, it may concern:

Be it known that I, MARTIN CHRIsTIANsnN, of Clinton, in the county of Rock and State of Wisconsin, yhave invented certain new and4 useful Improvements in Tile-Laying Attachments for Mole-Flows; and l do hereby declare that the following is a full, clear, and exact description of the invention, wh'ich'will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which' form a part of this specilication, and in which- Figure lis a side'view of a mole-plow provided with my improved tile-laying attachment, showing the device in Operation. Fig.

laying attachment, and Fig. 3 is apcrspective view of the last link of the attachment.

Similar letters ot' reference indicate corre-A sponding parts in all the figures.

My invention has relation to that class of tile-laying apparatus in which the tiles or drain-pipes are strung upon a chain composed of Vdetachable links, whichis attached to the rear end of a mole-plow,which opens a passage for the string of tiles, drawing them through the ground and placing them in position, whereupon the chain' is withdrawn from the string of tiles and again provided with a new set of tiles, which are placed in the same manner,and so forth; and it consists in the improved construction and combination of parts of such an apparatus, which may be attached to a common mole-plow, laying the tiles in the ditch or passage formed by the mole, as hereinafter In the accompanying drawings, the'letter A indicates the standard or cutterot` themoleplow, which is adj ustably securedin the hearn or sled B of the plow, to whichthe draft is attached, and G-indicates the handles, by means, of which the plow is guided, all of these parts, as well as' the mole D, being of any suitable construction, no claims being made for the same.

' A rearwardly and downwardly inclined standard, E, is secured with its bifurcated upper ends, FF, to the standard of the plow, projecting in the same planeas the standard and following inthe cut made by the same, and the lower end of this inclined standard is bent horizontally at alevel with the mole and l formed into two perforated lips, G... rlhe forward lat eye, H, of one of the links I is secured between these lips by means of a bolt, J, passing through the lips and the eye, and the eyes of the several links are hooked into each other, forming a chain. The links are preferably of the same length as the tiles K,

and truncate conical buttons or blocks L are secured upon the linksznear their end, the points of the blocks pointing rearward, and these blocks are of a diameter slightly less than the desired, and as long as the character of the soil will permit it to be dragged through it without causing too great a strain upon the chain or upon the plow or team, and the last link is provided upon its rear end with a long doublclconical block or button, M, of thesame diameter as the other blocks, and provided at its middle with two transverse parallel perforations, N N, one at each side of the longitudinal perforation with which it (its upon the straight portion of the link. The straight legs of a bent bail, O, are inserted through these perforations, the doubled end P of the bail being bent to form a hook, which may bear against the rear end of the last tile in the string, preventing the same fronislipping o from the chain.

When the device is put in operation, a hole is preferably made in the ground .to the depth desired for the ditch, and the plow with the inclined standard is placed into the hole,with the chain attached to the end of the standard and the tiles drawn upon the chain. As now the plow is propelled through the ground it will draw the string of tiles along-with it in the passage formed by the Inolc until the end of the chain is reached, when the plow has .preferably arrived to another hole made in thepoints'in a rearward direction assisting in the IOO free passage of the links through the tiles, and at the same time cleaning the tile from any dirt.

-' thus forming a continuous string.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In combination with a mole-plow, a rearwardly-inclined standard attached to the plow in a plane with the standard or cutter of the plow, and a chain formed of links of the same length as the tiles and having blocks or buttons upon them of the same diameter as the bores of the tiles, as and for the purpose shown and set forth.

2.' In a tilellaying attachment for moleplows, the'combination, with a rearwardly-inclined standard having perforated lips at its lower end, of a chain formed by links having straight portions and eyes hooked into each other at the ends, and having the foremost eye of the foremost link secured by a bolt between the lips of the standard and provided with truncate conical blocks or buttons near the eyed ends, having their points pointing in a rearward direction, as and for the purpose shown and set forth.

3. In a tiielaying attachment for moleplows, the combination of a link consisting of a straight rod having eyes at its ends, a truncate conical block or button, and a double truncate conical block or button havingtwo transverse parallel `pl'erforations at both sides of the perforation for'the link,and` having a bent bail with its legsinserted into the perfoe rations and its doubled bent end projecting forward, as and-for the purpose shown and set forth.

4. In a tile-layingattachment for moleplows, thecombination of'a rearwardly-inclined standard having a bifurcated upper end,

and havingl two perforated horizontal lips at links having eyes at their ends hooked into each other, and having the foremost eye of the foremost link vsecured by a bolt between the lips and provided with truncate conical blocks or buttons near their ends, .having'theirsmaller ends projecting rearward, and having a double truncate conical block or button upon the rear 5o 'its lower end, with a chain formed by straight the interior diameter of the tiles, and having their smaller ends pointing rearward, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto afxed my signature in presence of two witnesses. j MARTIN CHRISTIANSEN.
